Bakcup and Uplaod MongoDB to AWS S3

What can it do ?

A package to backup mongodb database to amazon s3 bucket

How do I get set up?

• Install the package npm install node-mongodump-s3
• Import it into your file
• Setup a backup client with your aws credential
• Initiate the backup

Notes about the generated dump

The generated mongo dump is an archive, so while restoring you should mark the --archive flag on

mongorestore --archive=/path/to/dump

Working example:

const mongoS3Backup = require("node-mongodump-s3");

const bucketName = process.env.AWS_S3_DUMP_BUCKET;
const accessKey = process.env.AWS_ACCESS_KEY_ID;
const accessSecret = process.env.AWS_SECRET_ACCESS_KEY;
const dbConnectionUri = process.env.MONGO_URI;

const backupClient = mongoS3Backup({ bucketName, accessKey, accessSecret });

backupClient
  .backupDatabase({
    uri: dbConnectionUri,
    backupName: "test_backup_" + Date.now(),
    prefix: "backups/",
  })
  .then((response) => {
    console.log("Success response ", response);
    /*
  Success response includes default aws response to uploading files
  example: 
    { 
      ETag: '"exampleEtag"',
      Location: 'https://examplebucket.s3.amazonaws.com/test_backup',
      key: 'test_backup',
      Key: 'test_backup',
      Bucket: 'mybucket' 
    }

*/
  })
  .catch((err) => {
    console.log("error is ", err);
  });

Possible options passed to backupDatabase method

• uri: string required the connection string for the mongo database `
• backupName: string required the name of the backup to be dumped on s3
• gzip: true|false wheather to use gzip option for the dump command, defaults to false

The package supports both promises & callback patterns
